Help please

Newbie here. I did a few mods using forscan on my 2022 f250 Lariat. Have two fully charged batteries everything works just can't get it started. I press the start button everything lights up but the truck doesn't do anything. Any forscan gurus

that could tell me where to start.

Not a Forscan guru, but have used it to do adjustments on my F350 and buddies F150. I didn't run into any issues, but on his I made a change and something just wasn't working right, been a bit, so don't remember exactly what. Key thing to do is save a baseline or download one if you didn't. I also logged every change and only dis one at a time, so backing up a step was fairly easy. For his, I reset back to stock configuration and then started the process over, just going slower and everything was good.

If you have your stock configuration, I would start by setting things back to that and see if that corrects your issues.

Good luck

check to see if both battery terminals are making good contact and check the voltage of both batteries....measure at the center of the battery terminal not on the battery clamps. if there is corrosion on the battery terminals the voltage will be different at the center of the terminals vs the clamps themselves.

also..mak sure your alarm is cleared...sometimes if you fiddle with the alrm on the key fob the truck goes into stupid mode and does nothing when you try to start it.
